我已经基于OAuth2创建了PasswdAuthenticationProvider界面的自定义实现。我认为代码与我遇到的问题无关，但是，它可以找到here。
我已使用以下属性配置hive-site.xml：
<property>
<name>hive.server2.authentication</name>
<value>CUSTOM</value>
</property>
<property>
<name>hive.server2.custom.authentication.class</name>
<value>com.telefonica.iot.cosmos.hive.authprovider.OAuth2AuthenticationProviderImpl</value>
</property>
然后我重新启动了Hive服务，并且我已成功连接基于JDBC的远程客户端。这是/var/log/hive/hiveserver2.log：

问题是以下错误以循环方式出现：

为什么呢？在使用默认值hive.server2.authentication（即SASL）时，我发现在其他几个问题中，客户端没有进行握手。但就我而言，这种属性的价值是CUSTOM。我无法理解，任何帮助都会非常感激。

我发现HiveServer2本身有来自HiveServer2的定期请求！这些是导致Thrift SASL错误的请求：
$ sudo tcpdump -i lo port 10000
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on lo, link-type EN10MB (Ethernet), capture size 65535 bytes

有什么想法吗？

有关从HiveServer2发送到HiveServer2的连接的更多研究。数据包总是发送5个字节，以下为（十六进制）：22 41 30 30 31
关于这些联系的任何想法？
答案 0 :(得分：0)
我终于“修复”了这个。由于消息是由在HiveServer2机器上运行的Ambari代理发送的（有些奇怪的ping版本），我只是添加了iptables规则，阻止了环回接口上TCP / 10000端口的所有连接：
iptables -A INPUT -i lo -p tcp --dport 10000 -j DROP
当然，现在Ambari警告说HiveServer2还没有存在（ping是droped）。如果我想从Ambari重新启动服务器（在启动脚本中有另一个活动检查），则必须删除上述规则;然后在重启后我可以再次启用规则。好吧，我可以忍受。
